Description

Issue Type: Bug

My esc key is mapped to jj and it works fine in many cases but i have a file where in the following things are written:

faajjkjldjflksafj;ljjfjskaljjjjjj:kdkdjjjjjjjjbbjjjldsfljjjjjjjjjjjjjjjjjjjjjjjjjjj

jjjjjjjjjj

when i press jj at the end of third line to go into escape mode, VSC becomes unresponsive. If i press jj somewhere else in the same file then it works fine.

Research direction
Investigate the Vim extension's input handling for the 'jj' escape sequence. Check for any regular expression or loop that could cause infinite recursion or blocking. Look at files such as src/actions/commands/actions.ts and src/modes/modeHandler.ts to understand how key sequences are processed. Reproduce the issue with the provided text to isolate the problematic pattern.
